Filed Oct. 14, 1968, Ser. No. 767,152 Int. Cl. B25c /02 US. Cl. 227-120 V 3 Claims ABSTRACT OF THE DISCLOSURE Improvements to a stapling machine having a base are shown which improvements include a pair of channels on opposite sides of the base, a guide member selectively fixedly disposed and slidably movable along the base, the guide member having an upstanding portion and a pair of downwardly depending sides which are normally outwardly spaced from the base. A hook is carried by one of the downwardly depending sides and normally abuts one of the channels. A screw is carried by the other of said depending sides and is selectively disposed and secured within the other channel.

This invention relates to improvements to a stapling machine particularly to a stapling machine of the longreach type.

In stapling machines it is generally desirable to have a guide member which is selectively positionable in various positions and is used to permit the operator of the machine to place a staple in the correct position on a sheet of paper spaced a fixed distance from one of the edges thereof.

(In certain other cases the use of such a guide mechanism is not desirable because varying types of papers are being stapled and the guide member involved will simply get in the way and prevent proper stapling from occurring.

It is an object of this invention to produce a guide device which is selectively slidably movable along the base of a stapling machine. The device may be selectively positioned at various points along the base if desired and fixedly positioned. Means are also provided for removing the guide device if the device is not desired.

The invention may be briefly described as comprising improvements to a stapling machine which has a base, a magazine overlying the base and abuttable therewith, and staple driving means within the magazine. The base carries channel portions on opposite sides thereof and a guide member having an upstanding portion thereupon and a pair of laterally disposed downwardly depending members is movable along the base. One of the downwardly depending members has a hook portion normally disposed within one of the channels and a screw member is carried by the the other of said downwardly depending members and is adapted to be selectively disposed and secured within the other of the channels. The guide member is selectively fixedly disposed and slidably movable along the channels depending upon the position of the screw member.

The invention will now be fiurther described by reference to the accompanying drawings which are made a part of this specification.

FIG. 1 is a side elevational view of a long-reach stapling machine carrying the improvements of this invention thereupon.

FIG. 2. is a fragmentary cross-sectional view of the guide member taken along lines 2-2 of FIG. 1. In this position the guide member is fixedly disposed upon the 3,523,634 Patented Aug. 11, 1970 ice base of the stapling machine since the screw member is abutting one of the channels.

FIG. 3 is a view similar to that of FIG. 2 but showing the screw member in spaced position from one of the channels so that the guide member is slidably movable therealong.

FIG. 4 is a view similar to that of FIGS. 2. and 3 but showing the position of the screw member which permits the guide portion to be completely removed from the base of the stapling machine.

The invention will now be further described by reference to the specific forms thereof shown in the accompanying drawings. In this connection, however, the reader is cautioned to note that the specific form of this invention as shown in the specification herein is for illustrative purposes and for purposes of example only. Various changes and modifications could obviously be made within the spirit and scope of this invention.

The stapling machine 11 of this invention is formed with a base 12 having a pair of oppositely disposed channels therewithin 15 and 16. A magazine 13 overlies the base in spaced relation therewith and a cap 14 overlies the magazine and constitutes staple driving means. Magazine 13 is pivotally connected to support 17 so that it can be selectively brought into abutting relationship with anvil 18 located on base 12.

A guide member 19 is formed with a body 20 and a pair of downwardly depending portions 24 and 25 which are normally spaced from the sides of base 12. A hook 22 is provided on guide member 24 and is inwardly disposed and normally lies within channel 15. An upstanding portion 21 is provided and is disposed on body 20.

A screw 23 is disposed within a threaded aperture located within downwardly depending member 25. Screw 23 bears a handle 27 thereupon.

With the foregoing specific description the operation of this invention can now be explained.

When it is desired to utilize guide 19 the parts are placed in the position shown in FIG. 3. It is noted that at this point screw 23 is retained within recess 16 and the entire guide member can be slidably moved along base .12. If it is desired to fixedly position the guide member at any point handle 27 is turned and the point of screw 23 is caused to abut the point of channel 16 as shown in FIG. 2. If it is desired to remove the entire guide member the screw 23 is placed in the position shown in FIG. 4 and, at that point, the downwardly depending portions will clear the sides of base 12 permitting the entire struc ture to be removed.

The foregoing sets forth the manner in which the objects of this invention are achieved.

We claim:

1. In a stapling machine having a base, a magazine overlying said base in normally spaced relationship therewith but selectively abuttable with said base, an anvil upon said base, and staple driving means operatively connected with said magazine, the improvement that comprises a pair of channels disposed upon opposite sides of said base, a guide member slidably mounted on said base having an upstanding portion thereupon and a pair of lateral downwardly depending members, one of said members having a hook portion normally disposed within one of said channels, a screw member threadedly carried by the other of said members and adapted to be selectively disposed and secured within the other of said channels.

2. The improvements as described in claim 1 including handle means carried by said screw member.

3. The improvements as described in claim 2 said downwardly depending portions being outwardly spaced from said channels and said hook portion being inwardly disposed.
